Background: The long-term outcomes of patients with autoimmune hepatitis (AIH) given the immunosuppressive treatment are considered to be preferable. However, little is known about the response of AIH patients with cirrhosis to immunosuppressive treatment. We assessed the effects of immunosuppressive therapy in Chinese AIH patients with cirrhosis from a tertiary hospital. Methods: Patients with a clinical diagnosis of AIH January 2000 and December 2015 were retrospectively reviewed. Two-hundred and fourteen patients who were followed up and satisfied the simplified AIH criteria were included in the study. Among these patients, 87 presented with cirrhosis when initially diagnosed for AIH. Immunosuppressive treatments were employed in 57 AIH patients who did not present with cirrhosis and 39 patients who presented with cirrhosis. Initial responses to immunosuppressive treatment of patients with and without cirrhosis were analyzed. Independent risk factors were assessed for predicting the prognosis of patients. The t-test and Cox regression statistical analysis were used. Results: In total, 96 AIH patients including 39 with cirrhosis and 57 without cirrhosis underwent immunosuppressive therapy. The overall complete remission after initial immunosuppressive treatment was achieved in 81/96 patients (84.4%), whereas 9/96 (9.4%) achieved incomplete response, and 6/96 (6.3%) occurred treatment failure. Compared to noncirrhotic patients, patients who presented with cirrhosis responded to treatment to a comparable extent regarding complete response (noncirrhosis 50/57 [87.7%] vs. cirrhosis 31/39 [79.5%], P = 0.275), incomplete remission (noncirrhosis 4/57 [7.0%] vs. cirrhosis 5/39 [12.8%], P = 0.338), and treatment failure (noncirrhosis 3/57 [5.3%] vs. cirrhosis 3/39 [7.7%], P = 0.629). Importantly, the remission rate was comparable (54/57 [94.7%] and 36/39 [92.3%], P = 0.629) for noncirrhotic and cirrhotic patients after immunosuppressive therapy. Compared to patients who maintained remission (n = 19) after drug withdrawal, patients who experienced relapse (n = 17) had significantly higher levels of serum immunoglobulin G at entry (15.0 ± 6.5 g/L vs. 22.3 ± 5.8 g/L, t = 2.814, P = 0.004). Moreover, cirrhosis at presentation significantly increased the risk of disease exacerbation (hazard ratio [HR]: 4.603; P = 0.002). The treatment of immunosuppressant (HR: 0.058; P = 0.005) and the level of aspartate aminotransferase at presentation (HR: 1.002; P = 0.017) also increased the risk of disease progression. Conclusions: The efficacy of initial immunosuppressive treatment in AIH patients with cirrhosis is comparable to that in those without cirrhosis. Cirrhotic patients not treated by immunosuppressants have poor long-term outcomes.
